Chapter 3, Problem 1E

Program Plan Intro

Print number series

Program plan:

• Create a class “PrintNumber”,
  • Define the method “printNumbers()” that accepts maximum number as an argument,
    • Print the numbers.
  • Define the method “main()”,
    • Call the method “printNumbers()” with an argument “15”.
    • Call the method “printNumbers()” with an argument “5”.

Program Description Answer

This program demonstrates the method that accepts maximum number as an argument and prints the number from “1” to that given maximum number.

Explanation of Solution

Program:

File name: “PrintNumber.java”

//Create a class

public class PrintNumber

{

    //Define the method "printNumbers()"

    public static void printNumbers(int number)

    {

        //Create loop to iterate over given number of times

        for (int n = 1; n <= number; n++)

        {

            //Print the current number

            System.out.print("[" + n + "] ");

        }

        //Print new line

        System.out.println();

    }

    //Define the main() method

    public static void main(String[] args)

    {

        //Print the string

System.out.println("The output for the call printNumbers(15) is: ");

        //Call the method with argument "15"

        printNumbers(15);

        //Print the string

System.out.println("The output for the call printNumbers(5) is: ");

        //Call the method with argument "5"

        printNumbers(5);

    }

}

Sample Output

Output:

The output for the call printNumbers(15) is:

[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15]

The output for the call printNumbers(5) is:

[1] [2] [3] [4] [5]
